CW generation up to 2 THz by ion-irradiated In0.53Ga0.47As photomixer driven at 1.55 µm wavelengths
Résumé
We report the generation of continuous terahertz waves from microwave frequencies up to 2 THz obtained by photomixing two optical waves at 1.55-mum wavelengths in an optimized ion-irradiated In 0.53 Ga 0.47 As interdigitated photomixers. Output powers greater than 40 nW at 0.5 THz and 10 nW at 1 THz have been achieved. The optimum excitation conditions regarding optical power and bias voltage are discussed
